FEED MECHANISM FOR PRINTING-MACHINES Specification of Letters Patent.

Patented Nov. 1c, 1915.

Application filed June 3, 1914. Serial No. 842,608.

To all whom it may concern Be it known that I, EDMUND OGUMPAUGH, a citizen of the United States of America, residing at Rochester, county of Monroe, and State of New York, have invented a new and useful Improvement in Feed Mechanism for Printing-Machines, of which the following is a full, clear, concise, and eXact description.

My invention relates to improvements in feed mechanism for use on check printing machines in which the check or other article is fed by means of rollers in a position where it may be printed by pressing it against raised type characters representing the different amounts to be printed on the check. This type may conveniently be arranged on a drum which may be rotated to place the set of type representing the amount to be printed beneath a blank space on the check provided for that purpose. The checks are preferably arranged in groups on a single sheet of paper with a perforation or tear line between them, and are fed in this state into the machine.

An object of my invention is to provide means for feeding the sheet of checks through the machine in a number of inde pendent movements, each movement being equal to the distance between adjacent printing positions on the sheet of checks.

Another object is to so arrange the check sheet feeding wheels that they can only be separated while in one position so that the sheet of checks will be properly started through the machine.

Another object is to provide automatic operating means for the feeding mechanism and also independent hand operating means therefor.

The several features and further advantages of my invention may be readily understood by reference to the accompanying drawings in which Figure 1 is a plan view of the mechanism; Fig. 2 is a left-hand side elevation of the mechanism with part of the side wall broken away; Fig. 3 is a cross-sectional side view taken on the line 33 of Fig. 1; Fig. 4 is a front elevation of the mechanism; Fig. 5 is a fragmentary perspective view of one pair of feed rollers and the adjusting mechanism; Fig. 6 is a fragmentary cross-section taken on the line 66 of Fig. 1; Fig. 7 is a cross-section taken on the line '7-7 of Fig.

1; Fig. 8 is a cross-section taken on the line 88 of Fig. 1; Fig. 9 is a perspective view of the back stop and guide plates.

Similar letters of reference refer to similar parts throughout the several views.

The check feeding mechanism consists of two pairs of feed rollers, 10 and 11, having their peripheries knurled and meshing with each other. The upper rollers 10 are secured to a shaft 12 which is mounted in supporting bearings 13 of a bridge piece 14:. An operating knob is secured to the righthand end of the shaft 12 for the manual-operation of the rollers.

The sheet of checks is moved to its various printing positions by turning the shaft 12 one complete revolution and in order to accurately gage this revolution of the feed rollers so that the check will not be fed too far or not far enough, I provide a stop ball 16 mountedin one of the bearings 13 and adapted, by means of a spring 17 and adj usting screw 18, to engage a registering socket or hole 19 in the adjacent feed roller 10. The lower feed rollers 11 are supported by means of individual levers 21-21 carried upon shaft 20 and are pressed against their mates by means of springs 2222 extending between the extensions 2323 of the lever 21-21 and the supporting plates 247-24. The shaft 20 is mounted in the side supporting plates 2l24: to which also is secured the'bridge piece 14.

After the first check has been fed into its printing position by hand, the succeeding checks will be fed automatically, each one by the action of the mechanism which was necessary for the printing of the preceding one.

The printing mechanism to which my invention may be applied consists of a rotatable drum 25 having on its surface, ar ranged longitudinally, raised type characters representing the different amounts of the checks to be printed, and a platen 26 adapted to press the check against the type by means of a plunger 27 attached thereto. This plunger is held in its non-operated position by means of a spring 28 nestedin the bore of an extension 29 forming part ofthe bridge piece 14. This plunger is operated by means of a suitable handle 30 pivoted at 31. In the return movement, to normal position, of this handle, under pressure of spring 28,'th'e sheet of checks is fed from one printing position to another. I provide, for that purpose, a gear segment 32 mounted on the side of the extension 29 and. adapted to participate in the movements of the handle 30 by means of a connecting link 33. Meshingwith segment 32 is a pinion 34 mounted loosely on shaft 12 as shown in Fig. 6 and having an enlarged portion 35 to which the spring-pressed pawl 36 is secured. The one tooth ratchet wheel 37 is secured to the shaft 12 and is adapted to be engaged by the pawl 36. On the depression of the handle for the printing of the first check, the gear segment revolves the pinion and pawl 36 one complete revolution, the pawl 36 passing over the tooth 38 on ratchet wheel 37. Upon the return movement of the handle, ratchet wheel 37 will be rotated one complete revolution and as it is afiixed to the shaft 12, the upper roller 10 will consequently also make a complete revolution, thereby feeding the sheet of checks into its next printing position.

The positioning of the sheet of checks is initially accomplished by separating the lower feed rollers 11 from contact with their mates. so that thesheet of checks may be moved between them by the pressure of the hand and, for that purpose, a lever and link mechanism consisting of the lever 39 attached to the shaft 20 and the lever 40 attached to a shaft 41 areprovided. The levers 39 and 40 are connected by link 42 and the lever 40 is provided with a handle for theoperation thereof, in the direction of the arrow, as shown in Figs. 2 and 5.

' In order that the cycle of operations will always be properly started, means are provided for preventing the separation of rollers 10 and 11 for the purpose of inserting a sheet of checks except when these rollers are in their initial positions. This means consists of a projection on the lever arm 40 which must register with the notch 44 in the disk 45 carried on shaft 10, in order that the movement of rollers 11 away from rollers 10 may be sufficient for the insertion of the paper between them.

The sheet of checks when placed in the machine" will be laid face downward on the table 46 and passed forward between the side runs 47 until the frontof the first check .touches the stop plate 48, which at this time has been lowered directly across the passageway. The lowering of this stop plate 48 takes place at the same time as the lower feed rollers are separated from their mates and is accomplished by means of levers 49 which are attached to shaft 41 engaging the plungers 50 attached to the stop plate 48 and which are normally holding the plate in a raised position out of the passageway of the checksby means of springs 51 surrounding the same, as shown in Figs. 7 and 8. The stop plate 48 is provided with lugs 52 adapted when the plate is lowered to project into corresponding apertures 53 in the table 46. hen the handle is released, the lower feed rollers return and press the check between the two pairs of rollers. The stop plate 48 is also raised out of the passageway of the check which is held close to the table at a point just in advance of the step plate by means of a depending guide plate or comb 54 attached to the bridge.

As it is obvious that many modifications could readily be made in the invention herein disclosed without departing from the spirit thereof, the apparatus should be taken merely as illustrative and the invention should be limited merely by the scope of the appended claims.

I claim:

1. In a paper feeding mechanism for check printing machines, the combination with a pair of normally registering rolls between which the paper is adapted to be fed, of manually operated means to rotate the rolls, independent manual means for separating said rolls, a stop operatively associated with the latter means and placed in the path of the paper when said latter means is oper* ated, whereby the paper may he slipped between said rolls to a point where it engages said stop, said stop being automatically removed from the path of the paper when said rolls engage the paper.

2. In a paper feed mechanism for check printing machines, the combination with a pair of rolls between which the paper is adapted to be fed, of means to separate said rolls so that the paper may be passed between them without rotating the rolls, and means to positively prevent such separation of the rolls except when one of said rolls is in a predetermined position, the circumference of said roll being such that one revolution of the roll feeds the paper from one printing position to another.

3. In a paper feed mechanism for check printing machines, the combination with a pair of rolls between which the paper is fed by the rotation of said rolls, of a stop mechanism adapted to be automatically set in the path of the paper to determine the location of the paper for its first printing position, and means holding one of said rolls against further rotation until said stop mechanism has been removed.

4. In a paper-feeding mechanism for check printing machines, the combination with a feed-roller, an idler roller and a spring for pressing the idler roller against the feed roller, a handle by means of which the idler roller may be moved out of engagement with the feed roller and means to prevent the rotation of the feed roller throughout the entire time during which the idler is thus moved out of engagement therewith.

. 5. In a paper feeding mechanism for check printing machines, the combination with a feed roller, an idler roller and a spring for pressing the idler roller against the feed roller, a handle by means of which the idler roller may be moved out of engagement with the feed roller, and means to prevent the operation of said handle when the feed roller is out of normal position.

6. In a paper feeding mechanism for check printing machines, the combination with a feed roller for the paper, a spring-pressed idler, means for rotating the feed roller, independent means to separate the idler from the feed roller so that the paper may be moved between them without the rotation of the feed roller, and means to prevent the rotation of the feed roller while the idler is thus separated therefrom.

7. In a printing machine, the combination with a paper feed roller adapted in one movement to advance the paper from one printing position to another of an idler roller for pressing the paper against the feed roller, means for moving the idler roller out of engagement with the feed roller and cooperating means for simultaneously engaging the feed roller to prevent the rotation thereof while the idler roller is thus moved out of engagement with the feed roller.

8. In a paper feeding mechanism for printing machines, the combination with a feed roller, an idler roller normally engaging said feed roller, a handle for moving the idler roller out of engagement with the feed roller and means made effective simultaneously with the movement of said idler roller out of engagement with the feed roller for preventing the rotation of the feed roller until, the idler roller is again brought into engagement with the feed roller.

In witness whereof, I hereunto subscribe my name this 14: day of May A. D., 1914.

EDMUND OGUMPAUGH.
